Question

67.17=((6.45+2x)^2)/((8.22-x)(-3x)^3)
ayúdame

Answer 1

Respuesta:

$67.17=\frac{\left(6.45+2x\right)^2}{\left(8.22-x\right)\left(-3x\right)^3}$

$\mathrm{Multiplicar\:ambos\:lados\:por\:}27x^3\left(8.22-x\right)$

$67.17\cdot \:27x^3\left(8.22-x\right)=-\frac{\left(6.45+2x\right)^2}{27x^3\left(8.22-x\right)}\cdot \:27x^3\left(8.22-x\right)$

simplificar

$1813.59x^3\left(8.22-x\right)=-41.6025-25.8x-4x^2$

resolver y resultado

$x\approx \:-0.13605\dots ,\:x\approx \:8.22052\dots$
